IMPROVEMENT IN TESTING INSTRUMENTS FOR BREWERS AND DISTILLERS.

The Schedule referred to in these Letters Patent and making part of the sme.

To all, whom tt may concern Be it known that I, MORITZ Auenxs'rnix, of Brooklyn, in the county of Kings and State of New York, have invented a new andvaluable Improvement A in Testing-Instruments for Brewersand Distillers; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation ofthe same, reference being had Yto the anneXed drawing making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawing is a front view of my sac'- charometer, with the door Opened.

-Fignres 2, 3, 5, and 6 are details 5 and Figure 4 is a .sectional view, showing the bulb ot the thermometer in its chamber.

My invention has relation to means i'or determining the relative density of beer, and thereby ascertaining the percentage ot' absolute alcohol in the fermented wort; and

It consists in certain improven'icnts upon the ordinary saccharometer, designed to render such instrument lnore efficient and accurate than it has heretofore been fouudto be in actual use.

These improvements consist-4 In the yuse of more thanvonc floating tube, whereby I am venabled to lessen its diameter, and to use within the space marking the same variation double the t number of graduating lines;

In the construction of the test-cup, whereby it is provided with a separate compartment for the reception. of the bulb of the thermometer, to which the beer has ready access through suitable perforations in the protecting partition, with a stout plate of brass separating the thermometer i'roin the becr-chauiber; and

In the construction ot the straining-tunnel with a series of graduated straincrs, and duly tinned for the better protection thereof from the action Of acids.

In such an instrument delicacy and accuracy of construct-ion and graduation are matters ot' paramount importance, in order to enable us to obtain results upon which we can rely as the basis of calculation.

The letter A of the drawing designates the test- 'cup or sample-taker, usually made Oi' copper.

B represents the cylindrical main compartment, into which the saccharoincter or floating tubeis introdnccd.

Extending vertically along one side of this com- `partmcnt is a smaller compartment, G, into which the liquid from the chamber B passes freely through a series of perforations, a, in the partition b, which allows it to move hack andi'orth from one chamber to the other.

The letter D represents a thermometer securely fixed-on the outer face of the plate c, which is usually of brass, and forms the front wall of compartment C.

This plate is forked at its lower end, and the neck of the thermometer passes thereby into the compartment C, and is turned upward, terminating in the bulb d.

The outer face of 'the plate e is graduated in de-A grees 'of Fahrenheit, and isalso provided with a correction-scale, graduated to hundredths of a degree of the saccharometer.

E represents a door, arranged to protect the thermometer; and

G, a non-conducting handle.

H is the base of the test-cup, which is usually weighted, and made non-conducting. It should have sn'icient area to secure the case, which is necessarily of some height, in an upright position.

K K represent the saccharometers or floating indicators. rlhey consist of weighted elliptical floats, from which extend upward the circular tubes e, closed at the top, and duly graduated to vmark tenths per cent. of sugar from 0- to 25 per cent.

One instrument is graduated from 0 to 12250 and the other, which is more weighty, from 12V to 250.

'Ihese instruments are graduated to 60 Fahrenheit, thereby facilitating the mathematical labor, ot' which their measurements form the basis, and which is `necessary in order to determine the percentage ot' absolute alcohol.

By using two instruments in place of one, I am enabled to make the hollow stem, which extends upward from the float, and lies partly within and partly without the mash, of smaller diameter, and also to use within the space marking the same variation double thc number of graduating lines, thereby enabling a more delicate test to be made, and a basis of calculation Vto be furnished which leads to a more acenrate result.

lhe system of graduationemployed is in accord with the decimal system of calculation.

L designates the straining-funnel, by means of which the bead and foreign matter are preventedV from passing into the test-cup.

This funnel consists of a hennsphei'ical cup, Z, from the bottom of which extends downward a short cylindrical tube, t, designed to be introduced into the mouth of the cylindrical compartment B of the testcup. p

m is a coarse strainer, hinged to the upper edge ot' thc cup Z, and resting on it in the manner of a concave perforated lid.

f is a hemispherical strainer of finer mesh, arranged within and parallel to the wall of the cup Z.

Below this, and 'across the tube t, is arrangeda hird strainer, s, of still finer perforations.

,lhesc different strainer-s, and the inner' wall of thc brass cup Z, and Jtube t, are protected from the action of acids by being formed of or coated with tin or other suitable material.

I olaim- Y -1. The test-cup A, having cylindrical chamber 15, bulb recess C, perforated partition I), graduated guardplate c, and thermometer D, substantially as specified.'

2. .lhe straining-funnel herein" described, having the upper and coarser strainer m hinged, the intermediate strainer q of similar shape to the funnel wall and parallel thereto, and the nest strainer s spauning the tube or spout, substantially as specified.

3. The complementarysaccharouieters K K herein described, graduated to tenths and. according to thc scale of 60 Fahrenheit, as specied.

4. 'lhe combination of the test-cup A, having cylinder chamber B, bulb recess C, guard-plate c, thermometer 1), and correction scale, with the complementary'saccharoineters K K, substantiallyY as shown and described.

5. llic instruments K 1i, graduated so as to show Y per cents. and fractions of per cents., and, adjusted to L `ahrenheits thermometer-scale, all substantially as` Witnesses:
